Note: In the pharmaceutical industry, pharmaceutical screening involves testing a large number of samples of substances to find those having desirable pharmacological activity; those samples which have the property sought are called active or positive in the screen. The substances tested may be pure compounds with known structure, mixtures of pure compounds, or complex mixtures obtained by extraction from living organisms. There are often additional sets of test performed on active samples, called
counterscreening to eliminate those samples that may also possess undesirable properties. In the case of screening of mixtures from living organisms, a type of counterscreening called dereplication is usually performed, to determine if the active sample contains a known compound which has previously been studied.

Screening, in medicine, is a strategy used in a population to identify the possible presence of an as-yet-undiagnosed disease in individuals without signs or symptoms. This can include individuals with pre-symptomatic or unrecognized symptomatic disease. As such, screening tests are somewhat unique in that they are performed on persons apparently in good health.
Screening interventions are designed to identify disease in a community early, thus enabling earlier intervention and management in the hope to reduce mortality and suffering from a disease. Although screening may lead to an earlier diagnosis, not all screening tests have been shown to benefit the person being screened; overdiagnosis, misdiagnosis, and creating a false sense of security are some potential adverse effects of screening. For these reasons, a test used in a screening program, especially for a disease with low incidence, must have good sensitivity in addition to acceptable specificity.
Several types of screening exist: universal screening involves screening of all individuals in a certain category (for example, all children of a certain age). Case finding involves screening a smaller group of people based on the presence of risk factors (for example, because a family member has been diagnosed with a hereditary disease). Screening interventions are not designed to be diagnostic, and often have significant rates of both false positive and false negative results.
Screening in economics refers to a strategy of combating adverse selection, one of the potential decision-making complications in cases of asymmetric information. The concept of screening was first developed by Michael Spence (1973), and should be distinguished from signalling, which implies that the informed agent moves first.
For purposes of screening, asymmetric information cases assume two economic agents—which we call, for example, Abel and Cain—where Abel knows more about himself than Cain knows about Abel. The agents are attempting to engage in some sort of transaction, often involving a long-term relationship, though that qualifier is not necessary. The "screener" (the one with less information, in this case, Cain) attempts to rectify this asymmetry by learning as much as he can about Abel.
The actual screening process depends on the nature of the scenario, but is usually closely connected with the future relationship.
In education economics, screening models are commonly contrasted with human capital theory. In a screening model used to determine an applicant's ability to learn, giving preference to applicants who have earned academic degrees reduces the employer's risk of hiring someone with a diminished capacity for learning.
